阅读更多关于 How do I specify relative file paths in restful web applications

问题 Deployment of my restful application will be "exploded" from a single WAR file. All file paths will need to be relative and not absolute (Nesting from a single WEB-INF directory). What is the convention for specifying these files (such as .properties files .xml files etc)? Example of wrongly specifying: file f = file(/usr/home/username/.../WEB-INF/file.something); Example of what I'm trying to achieve: (From Controller/Servlet) file f = new file(file.something); 回答1: You should NEVER specify

springMVC实现如何问WEB-INF下的JSP文件-- 01

阅读更多关于 springMVC实现如何问WEB-INF下的JSP文件-- 01

楼主是maven项目，平时若将jsp文件放入webapp(未放入WEB-INF下)，tomcat访问时只需http://127.0.0.1:8080/myHadoop/login.jsp即http://主机地址：端口号/项目名/文件名.jsp 即可访问然而，若将jsp文件放在WEB-INF目录下，则访问无法通过地址栏的输入进行访问因此本文旨在介绍如何用springMVC实现访问WEB-INF下的JSP文件springMVC的导包什么的就不细说了项目结构如下：首先在spring-servlet.xml配置文件中进行内部视图解析器的配置：首先在spring-servlet.xml配置文件中进行内部视图解析器的配置：这里配置的含义为加载视图解析器，如当发起login请求时添加前缀"/WEB-INF/views/" 后缀“.jsp” 配置完成后在web.xml文件中进行加载：接着，写一个控制跳转的controller（重要！） @RequestMapping("/") 含义请求会调用userLogin()方法返回的 login字符串会被上文提到的内部视图解析器进行前后缀拼接成 /WEB-INF/views/login.jsp 最终返回登录页面来源： CSDN 作者： YU_XIN_JAVA 链接： https://blog.csdn.net/JAVA_YU_XIN

struts2采用convention-plugin实现零配置

阅读更多关于 struts2采用convention-plugin实现零配置

最近开始关注struts2的新特性，从这个版本开始，Struts开始使用convention-plugin代替codebehind-plugin来实现struts的零配置。配置文件精简了，的确是简便了开发过程，但是，我们熟悉的配置突然disappear了，真是一下很不适应。跟着潮流走吧，看看该怎样来搞定convention-plugin。使用Convention插件，你需要将其JAR文件放到你应用的WEB-INF/lib目录中，你也可以在你Maven项目的POM文件中添加下面包依赖 Xml代码 < dependency > < groupId > org.apache.struts </ groupId > < artifactId > struts2-convention-plugin </ artifactId > < version > 2.1.6 </ version > </ dependency > 零配置并不是没有配置，而是通过约定大于配置的方式，大量通过约定来调度页面的跳转而使得配置大大减少。所以，首先应该了解下convention-plugin的约定： 1. 默认所有的结果页面都存储在WEB-INF/content下，你可以通过设置struts.convention.result.path这个属性的值来改变到其他路径。如： Xml代码 < constant

Struts2 零配置----详解

阅读更多关于 Struts2 零配置----详解

从struts2.1开始，struts2不再推荐使用Codebehind作为零配置插件，而是改为使用Convention插件来支持零配置，和Codebehind相比，Convention插件更彻底，该插件完全抛弃配置信息，不仅不需要是使用struts.xml文件进行配置，甚至不需要使用Annotation进行配置，而是由struts2根据约定自动配置。如何使用Convention 1. 将struts-Convention-plugin-2.1.6.jar文件复制到WEB-INF/lib路径下 2. 对于Convention插件而言，它会自动搜索位于action，actions，struts，struts2包下的所有java类，Convention插件会把如下两种java类当成Action处理： 1）所有实现了com.opensymphony.xwork2.Action的java类 2）所有类名以Action结尾的java类 3. Convention插件还允许设置如下三个常量： 1） struts.Convention.exclude.packges:指定不扫描哪些包下的java类，位于这些包结构下的java类将不会自动映射成Action； 2） struts.convention.package.locators
